The Institute of Catholic Culture has an app about our faith which is managed by Melkite Fr. Hezekias. The organization is dedicated to the re-evangelization of our society through educational and cultural programs offered to the public at no charge. You’ll find hundreds of hours of audio available for free on the app or on their website: instituteofcatholicculture.org. Their lectionary provides reflections (both Eastern and Roman Catholic) so you can better prepare yourself to attend Divine Liturgy.
